FORT WORTH-The family of an 8-year-old girl killed in a brutal hit and run almost three weeks ago is frustrated that there have been no arrests in the case.

Aja Hill was playing outside her home on Barron Lane when she was struck and killed on March 17.

A neighbor's surveillance camera caught footage of an obviously speeding Dogde Charger on the street just moments before Aja was hit.

Police located that car and even interviewed a person of interest in the first 72 hours after the accident, but no one has been arrested.

"Very frustrated, very frustrated," says Bobby Lewis Jr., the girl's uncle.

While he says the family appreciates that hit and run investigations can take time, it's a big break to get video evidence and find a car right away, evidence he thinks should lead to an arrest.

"We thought something was gonna' happen sooner than this. We feel like right now, it's just at a dead end," Lewis said.

A Fort Worth police spokesman said by email on Wednesday that the investigation is ongoing and " one has been ruled out, including the person of interest."

Police processed the car for physical evidence in the days after they confiscated it.

The family says they've been told it isn't immediately clear who was driving, but Lewis insists there has to be a way to find out quickly.

"I know who is driving my car. Everyone knows who drives their car," he said.

He hopes there is also an effort underway to find the driver of a white car seen in the surveillance video racing ahead of the suspect's. 

It's something Lyn Wofford wans to know, as well.

"It looks like he's chasing the other car, that is what we thought," she said.

It was the Wofford family that recorded the cars on their home security system.

Lyn was on a jog in the neighborhood when the accident happened.

She sprinted to the scene, and was one of the people to perform CPR on Aja.

"It's hard to think someone would hit a child and leave her in the street like that," she said.

The city has installed a series of stop signs in the area, that neighbors say have already proven effective at slowing drivers.

But at a community meeting expected for Thursday night, they are going to push for speed humps and more answers on the investigation.

"We need to come together," said Lewis.

The meeting is set for 6 p.m. Thursday at Dock Bookshop on Meadowbrook Drive.

Staff from the city, specifically District 4, are supposed to attend.
